U.S. Team Places Third at the 61st International Mathematical Olympiad

Washington, D.C. - Team USA, sponsored by the Mathematical Association of America American Mathematics Competitions (AMC), earned third place in the virtual 61st International Mathematical Olympiad (IMO) held on September 21-22, 2020. The six high school U.S. team members also won medals for their individual top scores.

The IMO, the preeminent high school math competition, brings together the top mathematics students from across the world to compete in the world championship of math. Each year, the competition is hosted by a different country, and this year it was originally scheduled to be held in St. Petersburg, Russia. For the first time in its history, the IMO was held virtually with each country setting up their own exam centers and live streaming the participants as they took the competition.

This year, over 600 students from 105 countries and territories competed. The U.S. team scored 183 points out of a possible 252 points. China won first place and Russia placed second in the overall team scores. IMO scores are based on the number of points scored by individual team members on six problems. On each day of the two-day competition, the teams have 4.5 hours to work on three problems.
